Airliner passenger suite seating arrangements with shared aisle suite access

ABSTRACT

A four-suite unit positionable in an aircraft cabin to one side of a longitudinal aisle and including first and second suites positioned longitudinally-aligned and facing each other, a shared passageway positioned between foot ends of the first and second suites, third and fourth suites positioned longitudinally-aligned and to one side of the respective first and second suites, a first passageway positioned between a portion of the first suite and a portion of the third suite for accessing the third suite from the shared passageway, and a second passageway positioned between a portion of the second suite and a portion of the fourth suite for accessing the fourth suite from the shared passageway.

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

The present invention relates generally to individual passenger suiteseating arrangements for airliners and other conveyances, and moreparticularly, to passenger suites arranged into groups and columns withshared lateral and branch aisles for accessing suites located apart fromlongitudinal aisles, as well as features and amenities associated withsuite groupings and individual suites.

Premium seating classes on long-haul international flights can includeindividual passenger suites equipped with lay-flat capable seats,ottomans, audio/video equipment and deployable tables, among otheramenities. Such suites can be found on wide-body jets where more spaceis available for accommodating the travel preferences of premium classpassengers who can afford to pay higher fares for more space, privacy,conveniences, and luxuries.

As with all seating classes, there is a need to arrange suites onairliners to maximize suite density without compromising seat space andprivacy. On current wide-body jets, suites can be arranged into a centercolumn and outboard columns, with suite access provided directly fromone of the longitudinal aisles that run from front to rear of theaircraft. As such, each suite is required to be positioned adjacent oneof these longitudinal aisles, or access to an outboard suite providedthrough an adjacent inboard suite, disadvantageously interrupting theprivacy of the passenger seated in the inboard suite. Such arrangementsalso limit the number of suites that can be positioned abreast and/orrequires the suites to be positioned at an angle to the longitudinalaxis of the aircraft.

Accordingly, what is needed are seating arrangements for individualsuites that allow a greater number of suites to be positioned abreast,thereby allowing all suites to extend in the longitudinal directionwhile maximizing suite privacy, among other advantages.

DETAILED DESCRIPTION

The present invention will now be described more fully hereinafter withreference to the accompanying drawings in which exemplary embodiments ofthe invention are shown. However, the invention may be embodied in manydifferent forms and should not be construed as limited to therepresentative embodiments set forth herein. The exemplary embodimentsare provided so that this disclosure will be both thorough and complete,and will fully convey the scope of the invention and enable one ofordinary skill in the art to make, use and practice the invention. Likereference numbers refer to like elements throughout the variousdrawings.

Each passenger suite shown in drawings and described herein is elongateand therefore defines a longitudinal suite axis and a lateral suiteaxis. The longitudinal suite axis of each suite can be oriented parallelto, or near parallel to, a longitudinal axis of the airliner, such thatall seats within the suites can be either forward facing or rearwardfacing. Flight attendant and galley components can be locatedimmediately forward and/or rearward of the columns of suites. Althoughthe seating arrangements disclosed herein show six suites arrangedabreast, alternate seating configurations are envisioned depending onthe width of the aircraft, among other factors.

FIGS. 1 and 2 show a first passenger seating arrangement 20 according toan embodiment of the invention. The first seating arrangement 20generally includes passenger suites arranged in a first outboard column22 (e.g., port side), a center column 24, and a second outboard column26 (e.g., starboard side). A first longitudinal aisle 28 is locatedbetween the first outboard column 22 and the center column 24. A secondlongitudinal aisle 30 is located between the center column 24 and thesecond outboard column 26. The first and second outboard columns 22, 26can be located against or adjacent a wall 32 of the aircraft fuselage,such that suites adjacent the wall 32 can be configured as windowsuites, and the suites adjacent one of the longitudinal aisles 28, 30can be configured as aisle suites. As used herein, the term“longitudinal” means the longitudinal direction of the aircraft (i.e.,front to rear), the term “inboard” means adjacent one of thelongitudinal aisles 28, 30, and the term “outboard” means apart from oneof the longitudinal aisles 28, 30, for example, adjacent the wall 32.

Each of the first outboard column 22, the center column 24, and thesecond outboard column 26 can be located between galley centers,lavatories, etc. As shown, the first and second outboard columns 22, 26have similar suite arrangements that differ from the suite arrangementin the center column 24. The seating arrangement, as it concerns thesuites in the first outboard column 22, center column 24, and secondoutboard column 26, is generally symmetrical about a longitudinalcenterline of the aircraft indicated at reference numeral 100.

The first and second outboard columns 22, 26 each include one or morefirst suite groupings 34 each generally including a first suite 36, asecond suite 38, a third suite 40, and a fourth suite 42, eachcomprising a lay-flat seat 44 extending in a longitudinal direction ofthe aircraft. The lay-flat seats 44 in the first and second suites 36,38 can be arranged laterally adjacent one another and can face, forexample, a rear of the aircraft. The lay-flat seats 44 in the third andfourth suites 40, 42 can be arranged laterally adjacent one another andcan face a front of the aircraft, for example. The seats 44 in the firstand third suites 36, 40 can be longitudinally aligned such that the seat44 of the first suite 36 faces directly into the seat 44 of the thirdsuite 40, although the suites are divided by partition walls asdiscussed below.

The second and fourth suites 38, 42 of each first suite grouping 34 arespaced apart in the longitudinal direction such that a lateral aisle 46is provided therebetween. Each lateral aisle 46 is accessible from oneof the two longitudinal aisles 28, 30 of the aircraft. Each lateralaisle 46 is located between the foot ends 48 of its respective secondand fourth suites 38, 42, and provides access to the outboard first andthird suites 36, 38. Thus, each lateral aisle 46 is shared by twopassengers to each access their respective outboard suite.

First and second branch aisles 50, 52 branch from each lateral aisle 46at the end of the lateral aisle 46 opposite one of the longitudinalaisles 28, 30. The first branch aisle 50 provides passage from itsrespective lateral aisle 46 to the first suite 36. The second branchaisle 52 provides passage from its respective lateral aisle 46 to thethird suite 40. Thus, while the lateral aisle 46 is shared for accessingboth the first and third suites 36, 40, each branch aisle 50, 52accesses only one of the first and third suites 36, 40. In thisarrangement, the first suite 36 is accessed by way of one of thelongitudinal aisles 28, 30, a lateral aisle 46, and a first branch aisle50. The third suite 40 is accessed by way of one of the longitudinalaisles 28, 30, a lateral aisle 46, and a second branch aisle 52. In thisarrangement, the first and third suites 36, 40 can be accessed withoutpassing through and disturbing the second and fourth suites 38, 42.

Each lateral aisle 46 can be oriented perpendicular to its respectiveone of the longitudinal aisles 28, 30. Preferably, each lateral aisle 46is oriented at a non-orthogonal angle to its respective one of thelongitudinal aisles 28, 30. The lateral aisles 46 can be oriented at ashallow angle to achieve an at least approximately 198 centimeter (i.e.,78 inch) suite length in each of the second and fourth suites 38, 42 toallow full seat recline to a flat bed. Maximum suite length can bemeasured from a suite wall behind the seat 44 to a farthest pointtherefrom at the foot end 48.

The foot ends 48 can be covered with a rounded or curved shroud 54 thatcovers a footwell. Opposite tapers of the spaced, opposing foot ends 48of the second and fourth suites 38, 42 allow the angled lateral aisle 46therebetween and achieve the minimum suite length requirement in ashorter length as compared to a suite arrangement having an orthogonallateral aisle orientation. The second and fourth suites 38, 42 havesubstantially equivalent lengths as measured from the wall behind theseat 44 to the farthest point of the foot end 48. All four suites 36,38, 40 and 42 can have the same length. Alternatively, a totallongitudinal length of the first suite 36 can be greater than a totallongitudinal length of the second suite 38, and a total longitudinallength of the third suite 40 can be greater than a total longitudinallength of the fourth suite 42.

The first and third suites 36, 40 are separated by a partition 56 thatdivides the suites and enhances privacy. A first side of the partition56 can be configured with at least one of a video monitor, a desk, adeployable table, and an ottoman presented for use by a passenger in thefirst suite 36. A second or opposite side of the partition 56 can beconfigured with at least one of a video monitor, a desk, a deployabletable, and an ottoman presented for use by a passenger in the thirdsuite 40. The second and fourth suites 38, 42 can also include at leastone of a video monitor, a desk, a deployable table, and an ottomanpositioned forward of their respective seat 44.

As further shown in FIGS. 1 and 2, the center column 24 can include aplurality of second suite groupings 58 each including a fifth suite 60and a sixth suite 62. The fifth and sixth suites 60, 62 can both beforward facing or both rear facing, and are generally symmetrical aboutthe centerline 100. Each of the fifth and sixth suites 60, 62 includes alay-flat seat 44 and a partition 64 spaced forward of the seat 44. Thepartition 64 can serve as a mounting location for at least one of adesk, video monitor, deployable table, etc. Lateral aisles 66 arelocated forward of the partitions 64 (i.e., between the partitions 64and the back of a “forward” suite) and provide access from one of thelongitudinal aisles 28, 30 to the other of the longitudinal aisles 28,30 without disturbing the occupants of the fifth and sixth suites 60,62.

Although the second suite grouping 58 is shown in the center column 24,at least one of the first outboard column 22, center column 24, andsecond outboard column 26 can include a second suite grouping 58. In anysuite grouping arrangement, each of the first outboard column 22, centercolumn 24, and second outboard column 26 include a plurality of one ofthe suite groupings disclosed herein.

FIGS. 3 and 4 shows first suite groupings 34 in the first and secondoutboard columns 22, 26, and a center column 24 including a plurality ofalternative second suite groupings 68. The alternative second suitegroupings 68 include laterally adjacent and longitudinally shifted firstand second columns 70, 72 of suites. The first column 70 includeslongitudinally adjacent suites each including a lay-flat seat 44extending in a longitudinal direction of the airliner, and the secondcolumn 72 includes spaced longitudinally adjacent suites each includinga lay-flat seat 44 extending in a longitudinal direction of theairliner. A lateral aisle 74 is provided between each of adjacent onesof the suites in the second column 72 for accessing a single one of thesuites of the first column 70 from one of the first and secondlongitudinal aisles 28, 30, or another onboard suite located across thecenterline 100. In the arrangement shown, the first and second columns70, 72 are symmetrical about the centerline 100, thus allowing access toeither laterally adjacent inboard suite from either one of thelongitudinal aisles 28, 30.

FIGS. 5 and 6 show a seating arrangement according to third embodimentof the invention. The seating arrangement shown includes a plurality ofsuites again arranged into a first outboard column 22, a center column24, and a second outboard column 26. Each of the first and secondoutboard columns 22, 26 includes two laterally adjacent first and secondcolumns 70, 72. The center column 24 includes four laterally adjacentcolumns in the order of, from port-to-starboard, a second column 72, afirst column 70, a first column 70, and a second column 72. The seatingarrangement also includes first and second longitudinal aisles 28, 30.

FIG. 7 shows a perspective view from within the first and second suites36, 38, wherein the first suite 36 is configured as a window suite andthe second suite 38 is configured as an aisle suite. The seats 44 withinthese suites are laterally adjacent and aligned. Each of the suites 36,38 includes a video monitor 76 positioned directly forward of the seat44, a shelf 78 located below the video monitor 76, a deployable traytable 80 located below the shelf 78, and an ottoman 82 located below thetray table 80. Vacant space is provided between the bottom of the traytable 80 and the top of the ottoman 82. In the case of the second suite38, the ottoman 82 therein can define a curvature along the backsidethereof that follows the curvature of the foot end. Thus, as shown, theottoman 82 in the second suite 38 is deeper on the “left side” ascompared to the “right side” as viewed in the drawing.

Seat controls in the form of a touchscreen controller 84 areincorporated into an angled surface at the end of a horizontal shelf orarmrest 86 that runs along the outboard wall of each of the suites 36,38. The padded ottoman 82 and padding running alongside the outboardwall of the suite can be substantially coplanar with the seatingsurfaces of the seat 44 when in a flat bed configuration to increase thesurface area of the bed. The touchscreen controller interface candisplay the adjustable seating surfaces and directional arrowsindicating directional movements of the adjustable seating surfaces. Thedisplay can further include touch keys for moving the seat to an uprightsitting position, predetermined reclined sitting position, and lay-flatsleeping position with a single touch. The controller 84 can furtherdisplay partition controls for raising and lowering a suite dividingpartition, as well as other control features.

FIG. 8 shows the angled lateral aisle 46 providing access to the branchaisles 50, 52, and ultimately to the respective first and third suites36, 40. The foot end 48 of each of the second and fourth suites 38, 42can be covered with the shroud 54 covering the footwell. The curvatureavoids sharp corners and snag hazards, and the opposite tapers allow anangled aisle and minimum seat length required for a bed configuration asdiscussed above. The partition 56 is also shown dividing the first andthird suites 36, 40.

FIGS. 9A and 9B are perspective views from within the first suite 36 toillustrate deployment and unfolding of the tray table 80. Each of thesuites can be equipped with a deployable tray table 80 configured tomove between a stowed position below the horizontal shelf 78, and adeployed use position apart from the shelf 78. Deployed use positionscan include positions over the seat 44 and positions forward of the seat44. Tray table 80 is supported on a support arm 88 configured to slidealong a horizontal rail 90 that runs along a wall of the suite.

The tray table 80 is cantilevered and horizontally oriented. Close-outs92 cover gaps between the primary and secondary top and bottom sectionsof the tray table 80, with the primary top section indicated at 94, theprimary bottom section at 96, the secondary top section at 98, and thesecondary top section at 102. The close-outs 92 can be hinged to theirrespective primary and secondary top and bottom sections such thatmovement of one section relative to another section causes the close-outhinges therebetween to move to permit section movement. The close-outs92 advantageously conceal pinch points and provide aesthetic coveringsfor the gaps when the tray table 80 is in a folded configuration.

FIG. 9A shows the tray table 80 deployed and folded, whereby theclose-outs 92 conceal the gaps between tray table sections. FIG. 9Bshows the tray table 80 unfolded and in an over-seat position. Primarytop section 94 is hinged to primary bottom section 96, while secondarytop section 98 is hinged to primary top section 94 and secondary bottomsection 102, and secondary bottom section 102 is hinged to primarybottom section 96. Pivoting the primary top section 94 apart from theprimary bottom section 96 causes secondary top and bottom sections 98,102 to pivot relative to each other to open the tray table 80 to form alarger horizontal tray table. The tray table 80 can be folded andunfolded as needed depending on the amount of surface area needed. Theyability of the tray table 80 to slide forward horizontally to a positionforward of the seat 44 allows seat egress without having to stow thetray table 80 and items thereon.

FIG. 10 shows a storage compartment 104 that can be located in spacebetween the video monitor 76 and the shelf 78. The storage compartment104 can have a hinged door 106, wherein a top edge pivots downward toopen as shown. The storage compartment 104 can be used to house powerand data connections, as well as include a compartment for storing aremote control and other items.

FIGS. 11A and 11B show a movable door 108 associated with one of thesecond and fourth suites 38, 42. The door 108 can be configured to slidehorizontally along a floor track to open and close. The door 108includes a vertical portion 110 that extends to about the top of theseatback of the seat 44, and an angled or canted top 112 that anglesinward away from the aisle. The angled top 112 enhances privacy in boththe open and closed positions of the door. The door 108 can include afront hole pattern 114 that allows internal illumination to shinethrough.

FIG. 12 shows a deployable partition 116 configured for use between thefirst and second suites 36, 38, the third and fourth suites 40, 42, andany other laterally adjacent suites. The partition 116 is configureddeploy to divide the adjacent suites and stow to connect the adjacentsuites. Movement between stowed and deployed positions can includeraising or lowering into the partition 118 between the suites,horizontal translation, pivoting movement, and combinations thereof.

FIG. 13 shows a storage tray 120 located above the video monitor. Thesides of the storage tray are formed by a combination of the tray 120itself and the partition walls 122 defining the suite boundaries. Thestorage tray 120 can be illuminated by way of a hole pattern andinternal illumination.

FIGS. 14 and 15 shows suites of the type found in the first and secondcolumns 70, 72. Suites in the first column 70 as shown can be configuredas window suites. Suites in the second column 72 as shown can beconfigured as aisle suites. The aisle suites in the second column 72 arespaced apart in the longitudinal direction to provide lateral aisles 74,each lateral aisle 74 accessing a single suite in the first column 70.Suites in the first column 70 can be spaced, not to provide an aisletherebetween, but to provide an area 124 laterally-adjacent a suite inthe second column 72 for use by the occupant in that suite. As shown,the area 124 includes a horizontal working area and two uprightsidewalls.

FIG. 15 shows a door 126 associated with suites in the second column 72located adjacent one of the longitudinal aisles 28, 30. The door 126 canhave a fabric panel construction including an integrally formed verticalportion 128 that extends from floor to top suite wall height, and acantilevered horizontal portion 130. In the open position of the doorshown in FIG. 15, the door stows alongside the video monitor 76 suchthat the horizontal portion 130 covers the top of the video monitor 76and the suite is accessible. In the closed position, the horizontalportion 130 covers a middle portion of the length of the suite, therebyclosing the suite and enhancing privacy. In a particular embodiment, thedoor 126 can be configured to travel to a position alongside the seat 44to provide a roof over the seat 44 for enhanced privacy.
